(Diagrams and microscope pictures of lily anthers.Dehisence is the term used to describe when the tapetum of the anther matures, dries out and breaks releasing the mature pollen grains from within the pollen sac.Remember the diploid cell in the pollen sac is a microspore due to its relatively small size as a gamete.)

(Microscope pictures of lily ovaries. The ovary of a lily actually contains 6 ovules each of which contains its own embryo sac. This is true of many plants and is the reason why you find several pips in the middle of an apple)
